Mixxx 2.5 Released

Tue 24 December 2024 Evelynne Veys 2.5, release announcement

All I want for DJ-ing is ...

Home alone? Scrooged? The sound of music? Die hard? Change plans: this year you will be having something better to do than watching old Christmas movies.

Mixxx is now your secret "Santa comin' to town", our elves had "good hearts with the burning desire to work hard", to get you "Rockin' around the Christmas tree at the party hop" with "something mighty sweet to see". "For the present, look high, not low": Mixxx's "presents 'neath the tree"

So this is the last goodbye ...

Important: OS-Support. macOS versions earlier than 11 can have a "Last Christmas". Windows versions earlier than version 10 build 1809 can be "Driving home for Christmas". For Ubuntu versions earlier than 22.04 "Christmas Will Break Your Heart".

By stepping over from Qt5 to Qt6 Mixxx is forced to increase the minimum system requirements to match those mandated by Qt. That's why the support has been dropped for macOS earlier than 11, Windows versions earlier then version 10 build 1889 and Ubuntu earlier then 22.04.

Let's cheer for the elves

Ho Ho Ho, our sleigh is filled with many shiny presents:

A red box filled with improvements to waveforms: 'SlipMode waveform' gives you visual aid while scratchin':

The 'beats until next marker' helps you to never miss the break:

The GL ES support makes the waveforms run smooth:

With a nice yellow bow around it, the new Skin & Interface features: the menubar can be hidden, reworked toggles (fullscreen, cue popup, vinyl control), improved tooltips, improved controls and checks (AutoDJ, effects), new command line interface options...

Our engine became a V8 sleigh: undo function for BPM/beats, beatloop anchor, rate tap button...

"Rudolph, the Red-Nosed Reindeer" will sound much better with the compressor and glitch effects and the improved backend, which now supports also native Audio Unit (AU) effect plugins on macOS.

Your "Jingles" and "Bells" can be sorted and found easier with the new library features: Cut, Copy and Paste in tracklists:

Tracks can be moved with Alt+Up/Down/PgUp/PgDn:

With a summary containing the number of tracks and the total duration added to the name of crates, playlists and historylists makes it easy to find the right list:

The searchengine received new BPM filters, an 'OR'-operator, new import possibilities, custom track colors for missing or played tracks...

"Santa Tell Me" what's new in preferences: some improved layout, the fetching of the soundcard's sample rate is fixed, a new setting for 'first hotcue', multiple options can be selected in the MIDI input editor.

Many "Days Of Christmas" full of improved Controller Mappings for Denon MC7000, Numark Scratch, Pioneer DDJ-FLX4, Traktor Kontrol S4 MK3 and MIDI for light.

A Controller Backend as a "Fairytale of New York" to map your controller: sysex, deck's track menu, support for bulk devices. We also dropped the lodash dependency.

Qt5 will Be Home For Christmas because Mixxx is using Qt6 now, a lot of work has been put in study, preparation, testing, upgrading procedures, adapting routines, dialogs, widgets, libraries. Upgrading to Qt6 wasn't just sitting "underneath the Mistletoe" but now Mixxx is in "Winter Wonderland". "Thank you Santa" Developers!

So many rafactorings have been made, improvements of the code by progressive insight, because of new possibilities in C++ and Qt, because of studies in acoustics, user experiences... The list is too long to write or make a selection here, it would be failing all contributors, you can find the complete list further in this announcement, full of "Christmas Lights".

So this is Christmas

"Baby, It's Cold Outside", so our present will be lots of fun exploring this new version. You'll need quiet some time to get used to all new features, discover the real possibilities, to get some adapted workflow with new handles. Mixxx whishes you a "Wonderful Christmas Time".

Mic drop, "Light the Candles All Around the World"

... and a happy 2.5
